Comparison of Monoclonal Napsin A, Polyclonal Napsin A, and TTF-1 for Determining Lung Origin in Metastatic Adenocarcinomas

A case of napsin A-positive metastatic lung cancer originating from the colon

BACKGROUND We report a case of napsin A-positive metastatic lung cancer originating from the colon. No cases of napsin A-positive metastatic lung tumors originating from colorectal cancer have been reported previously.

Non-small Cell Lung Carcinomas Lacking Morphologic Differentiation on Biopsy Specimens: Utility of an Immunohistochemical Panel Containing TTF-1, Napsin

Immunoexpression of napsin a in renal neoplasms

BACKGROUND Immunohistochemistry (IHC) for napsin A has been widely used to support a diagnosis of lung adenocarcinoma with high sensitivity. In this study, we evaluated immunoreactivity for napsin A in a broad spectrum of renal neoplasms by using tissue microarrays (TMA). METHODS Duplicate TMA of 159 surgically excised renal neoplasms of various types were constructed. IHC for napsin A was pe...
